Question

sum of zeroes of the polynomial x square _5x + 6​

Answer 1

Answer:

5

Step-by-step explanation:

assuming _ is -

we have to find the value of x so that $x^{2}$-5x+6 = 0

$x^{2}$-5x+6 can be written as

$x^{2}$-3x-2x+6 = 0

factorising

x(x-3)-2(x-3)=0

(x-2)(x-3)=0

therefore x = 2 or 3

therefore their sum is 2+3

=5

Answer 2

Answer:

=> x² - 5x + 6

=> x² - 2x - 3x + 6

=> x(x-2) - 3(x-2)

=> (x-2) (x-3)

x = 2 or x = 3

alpha =2  beta = 3

Sum of the zeros of the polynomial (alpha +beta)= 2+3 = 5
